Abstract (en)
[origin: WO9959929A1] An axial centrifugal device (1) for producing rock wool (8) from fibers (7) that are obtained from mineral melt (10) by means of a centrifugal force, generated by one or more, usually four, cascading rotating cylinders (3) with fronts shaped so as to form a fan that produces an additional radial air flow (13), which, combined with the axial air flow (12) from the blowing nozzles (6), produces a swirling air flow (9), thus determining a better and more uniform wetting of the mineral fibers by the binder and a better and more uniform mutual intertwining of the mineral fibers, and an additional axial air counter-flow (5), which reduces tearing of the layer of mineral fibers (7) already formed on the accumulation grid (2).
